Gopher2600 v0.13 is released. Gopher2600 is an emulator for the Atari 2600. Whilst the performance is not as efficient as some other emulators it is none-the-less suitable for playing games, on a reasonably modern computer, at the required 60fps. (The development machine for Gopher2600 has been an i3-3225, dating from around 2012.)

Gopher2600 v0.13 changelog:
ARM7
- Counting of PC access no longer assumed to be in Flash or MAM. Can be in SRAM too
- Counting of data access no longer assumed to be in SRAM

- format 15 CMP instruction did not set status flags correctly
ARM7 model selectable
- Models supported: LCP2000, STM32F407VGT6
- Memory map only. Other performance characteristics might be different
- Work in progress: change through config file
Debugger/Disassembler
- Disassembly path detection improved
- Corrected use of read symbols used in disassembly. Write symbols were
used in error in some situations.
MNetwork (E7) fingerprinting accuracy
TV
- CRT ghosting now only applied horizontally
- settings for ghosting in CRT preferences
- Frame size detection less aggressive
- Screen roll sensitivity preference
Multiple gamepads/sticks supported
- All control player zero currently
- Other players will be supported once a suitable mechanism for
allocating controllers has been settled on
